[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] Reference below Figure 1-Figure 6 An adjustment mechanism 100 for a display screen 200 according to an embodiment of the present invention is described.

[0044] like Figure 1-Figure 6 As shown, an adjustment mechanism 100 according to an embodiment of the present invention includes: a fixed bracket 10, a movable mobile module 20, a rotatable rotating module 30 and a driving device 40, one of the mobile module 20 and the rotating module 30 is arranged on the fixed bracket 10, and the other of the mobile module 20 and the rotating module 30 is used to connect to the display screen 200, and the mobile module 20 and the rotating module 30 are connected, which can be a direct connection or a transmission connection through a transmission component.

[0045] For example, the mobile module 20 is arranged on the fixed bracket 10, and the mobile module 20 can move relative to the fixed bracket 10; the rotating module 30 is rotatably arranged on the mobile module 20, and the rotating module 30 can be connected to the display screen 200, that is, the display screen 200 is installed on the rotating module 30, and the rotating module 30 drives the display screen 200 to rotate when it rotates. Since the rotating module 30 is arranged on the mobile module 20, when the mobile module 20 moves, it can drive the display screen 200 to move.

[0046] For another example, the rotating module 30 is disposed on the fixed bracket 10, and the movable module 20 is connected to the display screen 200. When the movable module 20 moves, the display screen 200 moves. When the rotating module 30 rotates, the display screen 200 can also rotate.

[0047] The driving device 40 cooperates with the mobile module 20 and the rotating module 30. The driving device 40 can drive the mobile module 20 to move and drive the rotating module 30 to rotate, so that the display screen 200 switches between a first state and a second state. The first state here can be a horizontal screen state, and the second state can be a vertical screen state, or the first state can be a vertical screen state, and the second state can be a horizontal screen state. The driving device 40 can be one, and the driving device 40 simultaneously drives the mobile module 20 to move and the rotating module 30 to rotate. The driving device 40 can also be two, and the two driving devices 40 drive the mobile module 20 and the rotating module 30 respectively.

[0048] That is to say, when the display screen 200 switches states, under the action of the driving device 40, the rotating module 30 drives the display screen 200 to rotate, and the moving module 20 drives the display screen 200 to rise and fall, so that the display screen 200 can rotate and move. For example, when the display screen 200 switches from the first state to the second state, the display screen 200 can rotate and descend at the same time, and then when it switches to the second state, the upper edge of the display screen 200 will not be too high to affect the driving line of sight; when the display screen 200 switches from the second state to the first state, the display screen 200 can rotate and move upward, so that when it switches to the first state, the height can be adjusted to achieve a better display viewing angle and provide a comfortable use experience. The driving device 40 may include a driving motor 41, and the driving motor 41 is externally connected to a power supply so that the adjustment mechanism 100 can be electrically controlled. The driving device 40 can also be manually driven to adjust the display screen 200.

[0049] According to the adjustment mechanism 100 of the embodiment of the present invention, the driving device 40 drives the mobile module 20 and the rotating module 30, providing a compound movement of rotation and movement. The display screen 200 can be switched between the first state and the second state. At the same time, the display screen 200 can adjust the moving position to achieve a suitable display viewing angle when switching between the first and second states, providing a safe and comfortable use experience of the mobile module; by setting the mobile module 20 and the rotating module 30, movement and rotation can be relatively independent, which is conducive to providing more states, realizing more complex movements and positioning, and improving the reliability of the system.

[0050] Among them, the fixed bracket 10 here can be directly installed on the body of the vehicle, or it can be integrally formed with a part of the structure of the body. The display screen 200 here can be a vehicle-mounted display screen 200; the display screen 200 can be arbitrarily adjusted to the first state or the second state according to the needs of the vehicle user, and the position of the display screen 200 in the height direction is also adjusted to enhance the experience of the vehicle user.

[0051] In addition, the driving device 40 may include a driving motor 41 and a transmission assembly 42. A part of the transmission assembly 42 cooperates with the rotating module 30, and a part of the transmission assembly 42 cooperates with the moving module 20, so that the driving motor 41 drives the moving module 20 to move and the rotating disk 31 rotates synchronously. Therefore, under the action of one driving motor 41, the rotating module 30 and the moving module 20 are driven to move, and the rotating motion and the lifting motion are performed synchronously, thereby improving the adjustment efficiency; at the same time, the number of driving motors 41 is reduced, the manufacturing cost is reduced, the compactness of the structure can be improved, the assembly space can be saved, and the transmission efficiency and transmission accuracy of the system can be improved.

[0052] like Figure 1-Figure 5 As shown, in some embodiments, the mobile module 20 moves along a first direction (eg Figure 2 The extending direction of the rotation axis of the rotating module 30 is the second direction (as shown in the upper and lower directions). Figure 2 The first direction is perpendicular to the second direction, so that the rotation of the display screen 200 will not interfere with the movement of the moving module 20, and the rotation axis of the rotating module 30 can be perpendicular to the display screen 200 and coincide with the geometric center of the display screen 200, thereby facilitating the connection between the display screen 200 and the rotating module 30. At the same time, the center of the display screen 200 is connected to the rotating module 30. Compared with the case where the rotation axis of the rotating module 30 deviates from the geometric center of the display screen 200, the stability of the display screen 200 can be improved and the probability of shaking of the display screen 200 can be reduced.

[0053] like Figure 1 and Figure 2As shown, in some embodiments, the mobile module 20 includes a mobile body 21 and a rotating member 22, the rotating member 22 is rotatably connected to the mobile body 21, and the driving device 40 is arranged on the mobile body 21. The driving device 40 can drive the rotating member 22 to rotate to drive the mobile module 20 to move, that is, the driving device 40 is integrated on the mobile module 20, and the driving device 40 does not need to be installed on the fixed bracket 10, thereby reducing the complexity of the structure of the fixed bracket 10, and at the same time facilitates the driving device 40 to cooperate with the rotating module 30 to drive the rotating module 30 to rotate synchronously.

[0054] like Figure 2 and Figure 4 As shown, in some embodiments, a rotatable screw 11 is provided on the fixed bracket 10, and the rotating member 22 is threadedly matched with the screw 11. The driving device 40 can drive the rotating member 22 to rotate, thereby driving the screw 11 to rotate. Since the rotating member 22 is provided on the mobile body 21, the rotating member 22 can only rotate relative to the mobile body 21, and the mobile body 21 can move relative to the fixed bracket 10. Therefore, when the screw 11 rotates, the rotating member 22 itself rotates, so that the position of the rotating member 22 on the screw 11 changes, thereby driving the mobile body 21 to move relative to the screw 11, thereby realizing the lifting and lowering drive of the mobile module 20 by the driving device 40, and the overall structure is compact.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the rotating module 30 includes a rotating disk 31 and a connecting member 32, the rotating disk 31 is used to install the display screen 200, the connecting member 32 is connected to the rotating disk 31, and the driving device 40 cooperates with the connecting member 32 to drive the connecting member 32 to rotate, drive the rotating disk 31 to rotate, and then make the display screen 200 rotatable.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, the driving device 40 includes a driving motor 41 and a transmission assembly 42, the driving motor 41 cooperates with the transmission assembly 42, the transmission assembly 42 at least includes a first worm 421 and a ring gear 422, the ring gear 422 is sleeved on the first worm 421, and the ring gear 422 rotates synchronously with the first worm 421, the helical teeth of the first worm 421 are engaged with the connecting member 32 to drive the connecting member 32 and the rotating disk 31 to rotate, the ring gear 422 cooperates with the rotating member 22 to drive the rotating member 22 to rotate, thereby under the action of the first worm 421 and the ring gear 422, the driving motor 41 can simultaneously drive the connecting member 32 to rotate and the rotating member 22 to rotate, the rotation of the connecting member 32 drives the rotating disk 31 and the display screen 200 to rotate, the rotation of the rotating member 22 drives the moving body 21 to move, thereby realizing the rotation and synchronous movement of the display screen 200.

[0057] Among them, the ring gear 422 and the first worm 421 can be integrally formed, or they can be designed separately and assembled into an integrated structure, for example, the ring gear 422 and the first worm 421 have an interference fit, etc.; in addition, a rotating gear 221 can be provided on the outer periphery of the rotating member 22, and the ring gear 422 can directly mesh with the rotating gear 221, or it can cooperate with the rotating gear 221 by adding one or more gears 423.

[0058] Therefore, under the action of a driving motor 41, the connecting member 32 and the rotating member 22 are driven to move, and the rotation movement and the lifting movement of the display screen 200 are performed synchronously, thereby improving the adjustment efficiency; at the same time, the number of driving motors 41 is reduced, the manufacturing cost is reduced, the compactness of the structure is improved, the assembly space is saved, and the transmission efficiency and transmission accuracy of the system are improved; by adopting the first worm 421 with a ring gear 422 for transmission, it has a certain self-locking property, which makes the entire drive more stable.

[0059] like Figure 3 As shown, in some embodiments, a second worm 411 is provided at the output end of the driving motor 41, and the second worm 411 is meshed with the first worm 421 through a gear ring 422, and the axial direction of the second worm 411 is perpendicular to the axial direction of the first worm 421, so that the driving motor 41 can be horizontally arranged on one side of the axial direction of the first worm 421, thereby reducing the space occupied by the driving device 40 as a whole in the axial direction of the first worm 421, improving the compactness of the structure, and facilitating the installation of the driving motor 41 as a whole in the mobile body 21.

[0060] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the mobile body 21 has a mounting column 211, a mounting hole 212 is provided in the middle of the mounting column 211, and the rotating disk 31 has a rotating shaft 311. The rotating shaft 311 can extend into the mounting hole 212, and the rotating shaft 311 can rotate relative to the mounting column 211, so that the mounting column 211 can play a certain guiding and supporting role for the rotating disk 31, and the rotating disk 31 can rotate in the mounting column 211, thereby reducing the probability of displacement of the rotating disk 31, while improving the stability of the rotating disk 31 during rotation and reducing the probability of shaking of the rotating disk 31.

[0061] The connecting member 32 is arranged on the outside of the mounting column 211, and the connecting member 32 can rotate relative to the mounting column 211, that is, the connecting member 32 and the rotating shaft 311 are respectively located on the inner and outer sides of the mounting column 211, and the connecting member 32 can be a connecting sleeve arranged on the outer periphery of the mounting column 211, and the side of the connecting member 32 close to the rotating disk 31 is connected to the rotating disk 31. For example, one end of the connecting member 32 has a locking protrusion 321, and the rotating disk 31 has a locking groove, and the locking protrusion 321 can be inserted into the locking groove. The first worm 421 of the driving device 40 is used to drive the connecting member 32 to rotate. Since the rotating disk 31 is connected to the connecting member 32, the rotating disk 31 can be driven to rotate, thereby realizing the rotation of the display screen 200.

[0062] By arranging the connecting member 32 and the rotating shaft 311 on the inner and outer sides of the mounting column 211 respectively, it is convenient for the first worm gear 421 to cooperate with the connecting member 32, and a slot structure can be formed after the connecting member 32 is connected to the rotating disk 31. The mounting column 211 is inserted into the slot, thereby improving the reliability of the cooperation between the rotating module 30 and the mounting column 211, and the overall structure is compact and reasonable.

[0063] like Figure 4 and Figure 5 As shown, in some embodiments, one end of the rotating shaft 311 extends out of the movable body 21, and a locking ring 33 is provided on the extended end, and a locking spring 34 is provided between the locking ring 33 and the outer wall surface of the movable body 21, and the locking spring 34 is used to limit the position of the locking ring 33 relative to the movable body 21. Specifically, when the rotating disk 31 is installed, the rotating shaft 311 is extended into the mounting column 211 until the end of the rotating shaft 311 extends out, and a locking spring 34, or a gasket 35 and a locking spring 34 are sleeved on the rotating shaft 311, and then the locking ring 33 is clamped on the rotating shaft 311. Here, a mounting groove can be provided on the rotating shaft 311, and the mounting groove of the locking ring 33 is clamped so that the locking spring 34 is pressed between the locking ring 33 and the gasket 35, or between the locking ring 33 and the outer wall surface of the movable body 21, thereby improving the reliability of the installation of the rotating disk 31, and the locking spring 34 can play the role of anti-loosening, buffering and shock-absorbing in the connection.

[0064] like Figure 2 As shown, in some embodiments, the rotating disk 31 has a first limit member 36, the moving body 21 has a second limit member, and the driving device 40 drives the rotating disk 31 to rotate until the first limit member 36 and the second limit member cooperate, that is, under the drive of the driving device 40, through the cooperation of the two limit members, the limiting and self-locking effects after they are in place can be achieved, preventing the driving device 40 from continuing to work, causing the rotating disk 31 to continue to rotate, the moving body 21 to continue to move, causing structural damage, etc., thereby making the rotation angle and moving stroke of the display screen 200 accurate, and self-locking can be achieved during the movement and after it is in place.

[0065] In some embodiments, a third limit member is provided on the mobile body 21, and a fourth limit member is provided on the fixed bracket 10. Under the drive of the driving device 40, the mobile module 20 moves until the third limit member and the fourth limit member abut and cooperate with each other, so as to realize the limiting and self-locking effects after being in place, and prevent the driving device 40 from continuing to work, causing the rotating disk 31 to continue to rotate, the mobile body 21 to continue to move, and cause structural damage, etc., thereby making the rotation angle and moving stroke of the display screen 200 accurate, and realizing self-locking during the movement and after being in place.

[0066] like Figure 2 and Figure 4 As shown, in some embodiments, the mobile body 21 defines an installation cavity 213, the rotating member 22 is rotatably disposed in the installation cavity 213, the driving device 40 is disposed in the installation cavity 213, and the mobile body 21 can be a box-shaped structure. The mobile body 21 includes a first shell 2101 and a second shell 2102, and the two shells can be connected by fasteners. An installation cavity 213 is defined between the two shells, so that the driving device 40, the rotating member 22, etc. can all be installed in the installation cavity 213. The mobile body 21 can protect each structure and improve the compactness and aesthetics of the structure.

[0067] In addition, a circuit board 60 may be installed on the mobile body 21 , and the circuit board 60 is electrically connected to the driving device 40 . The circuit board 60 may be disposed in the installation cavity 213 or may be installed outside the mobile body 21 .

[0068] like Figure 2 As shown, in some embodiments, a slide groove 12 is provided on the fixed bracket 10, and a slider 214 is provided on the outer side of the mobile body 21. The slider 214 can be inserted into the slide groove 12, and the slider 214 slides with the slide groove 12. The extension direction of the slide groove 12 is the same as the moving direction of the mobile module 20. Therefore, when the mobile module 20 moves in the vertical direction, it has good guiding performance, making the movement more stable, and the overall structure is simple and easy to process and manufacture.

[0069] The slider 214 can also roll with the slide groove 12 through a roller to further reduce noise.

[0070] The slide groove 12 may include two slide blocks 214 that are arranged opposite to each other. The cooperation between the two slide blocks 214 and the slide groove 12 further improves the stability. The parallel-designed slide blocks 214 and the slide groove 12 are easy to process and the parallelism is easy to control.

[0071] like Figure 2As shown, in some embodiments, the adjustment mechanism 100 also includes: a tension spring 50, one end of the tension spring 50 is connected to the mobile module 20, and the other end of the tension spring 50 is connected to the fixed bracket 10, and the tension spring is suitable for providing tension to the mobile module 20 when the mobile module 20 moves. By using the tension spring 50 to connect the mobile module 20 and the fixed bracket 10, when the mobile module 20 moves in the vertical direction, the tension spring 50 can provide tension to achieve a buffering and shock-absorbing effect, making the movement process smoother, and when the switching position system is locked, the tension spring 50 can provide a certain pre-tightening force to reduce the gap between related parts, thereby achieving the effect of preventing loosening and reducing noise.

[0072] According to an embodiment of the present invention, the vehicle includes a display screen 200 and an adjustment mechanism 100 according to an embodiment of the present invention. The rotating module 30 or the moving module 20 of the adjustment mechanism 100 is connected to the display screen 200. By adopting the above-mentioned adjustment mechanism 100, the display screen 200 can be switched to a horizontal second state. At the same time, when the display screen 200 switches between the first state and the second state, it can adjust the moving position to achieve a suitable display viewing angle, thereby providing a safe and comfortable use experience.

[0073] like Figure 6 As shown, in some embodiments, when the driving device 40 drives the rotating module 30 to rotate and switches the display screen 200 from the first state to the second state, the moving module 20 moves downward, and the rotation axis of the rotating module 30 can be perpendicular to the display screen 200 and coincide with the geometric center of the display screen 200. Figure a shows when the display screen 200 is in the first state, and Figure b shows when the display screen 200 is in the second state. The moving module 20 moves downward, driving the geometric center of the display screen 200 to move downward, so that the upper edge of the display screen 200 is not too high when the display screen 200 switches to the second state, thereby avoiding the switching of the display screen 200 affecting the user's line of sight.

[0074] like Figure 6 As shown, the display screen 200 is roughly rectangular, and the upper edge of the display screen 200 in the first state and the upper edge of the display screen 200 in the second state are at the same height, so that the upper edge of the display screen 200 will not be too high to affect the driving line of sight. The display screen 200 can always be maintained at a suitable height position to achieve a suitable display viewing angle, providing a safe and comfortable use experience.

[0075] like Figure 7 As shown, the control method of the display screen according to the embodiment of the present invention includes:

[0076] S1, receiving the switching instruction of the display screen;

[0077] S2, the driving device works to control the moving module to move and the rotating module to rotate.

[0078] According to the control method of the display screen of the embodiment of the present invention, when a switching instruction is received, the driving device drives the moving module and the rotating module to move, so that the display screen can switch to the second horizontal state. At the same time, when the display screen switches between the first state and the second state, the moving position can be adjusted to achieve a suitable display viewing angle, providing a safe and comfortable use experience.

[0079] In some embodiments, after controlling the moving module to move and the rotating module to rotate, the method further includes:

[0080] S3, judging whether the display screen has reached the desired position;

[0081] S4, when the display screen moves into place, controlling the adaptive adjustment of the displayed content.

[0082] The switching instruction here can be any one of a button, voice, or gesture.

[0083] In addition, the judgment of whether the display screen has moved to the right position can be to detect the information of the driving device, such as detecting the current of the driving motor. Since the driving motor will be blocked after the rotating module rotates to the right position (the first limiter on the rotating module and the second limiter on the moving module cooperate to limit the further rotation of the driving motor), the current of the driving motor will suddenly increase. By detecting the change in current, it can be determined that the display screen has moved to the right position. Of course, it is also possible to set a sensor to detect whether the display screen has moved to the right position.

[0084] According to the control method of the display screen in the embodiment of the present invention, after the display screen moves into place, the display content is adaptively adjusted, which can further improve the user experience.

[0085] In some specific embodiments, when receiving the instruction to switch the display screen 200, the driving motor 41 of the driving device 40 starts to work, and after the first worm 421 and the second worm 411 are decelerated and torque-increased, the power is transmitted to the connecting member 32 of the rotating module 30, and the connecting member 32 is connected to the rotating disk 31 through the cam 321, driving the rotating disk 31 to rotate, and the ring gear 422 on the second worm 411 transmits the power to the rotating gear 221 of the rotating member 22 through the gear 423, and then transmits it to the screw 11. Under the guidance of the slide groove 12 of the fixed bracket 10, the movement of the screw 11 causes the entire driving device 40, the mobile module 20, and the rotating module 30 to move vertically downward relative to the fixed bracket 10. When the rotating disk 31 rotates to the right position, the first limit member 36 on the rotating disk 31 cooperates with the second limit member of the mobile body 21 to block the rotation, the motor stops moving, the entire mechanism is locked, and the movement is completed; the movement in the opposite direction only needs to change the direction of the motor, thereby realizing the composite movement of the rotating disk 31 in the rotation and vertical direction.

[0086] Other components and operations of the vehicle according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail herein. The up-down direction, left-right direction and front-back direction are based on the up-down direction, left-right direction and front-back direction shown in the figure.
